sys-devel/automake: Provide pkg_setup to call python_setup only when FEATURES=test is set

Previous attempt cfaa5ec192 was reverted in commit
cd0e6915f3 to avoid unnecessary mass rebuild for
"--changed-deps=y" users which was possible because dependencies were fine.

Package was only failing at build time in pkg_setup when Python 2.7 wasn't
available because eclass exports pkg_setup.

Bug: https://bugs.gentoo.org/648940
Package-Manager: Portage-2.3.24, Repoman-2.3.6
